Do you want the motor to behave like a turbo-charger(throttle) or cruise control? I would like to use power assist to function like a transmission. Match torque to RPM.
My main route is 2700m or 1.7 miles and 600 foot elevation change. My trip is entirely up or down a canyon, not rolling hills:
This approach requires buying the Bike and BBS02 from a local shop, on the same day. Make a return trip to customize the PAL settings. I do not see how this can be accomplished from Internet purchases, because you will not know required wattage before ordering the BBS02.

A power meter will indicate which column in the above table corresponds with your leg strength.
The folks at Cycle Analyst sent this helpful link for power meters. Many options exist according to his article:
"These units don’t actually measure your work effort using strain gauges, but instead rely upon other environmental factors. Thus the name of non-Direct Force Power Meters (DFPM).
PowerCal: The PowerTap PowerCal (offered in both ANT+ and Bluetooth Smart) is a heart-rate strap that also transmits power information. It monitors your heart rate and then uses the rate of change to determine power. While many hard-core power meter users are afraid to even glance at the thing, I found that when you started looking at real-world data, it wasn’t actually all that bad. And in fact, it was far more accurate than you’d expect. In general, I’d recommend this for someone that may be buying a heart rate strap anyway and is interested in power (since you’re basically just spending $50 more, it’s about $99 these days).

- 10% grade for 400m
- 02% grade for 400m - power unnecessary.
- 18% grade for 250m
- 10% grade for 200m
- 05% grade for 500m
- 02% grade for 1000m - power unnecessary.
- would configuring PALs to hill steepness optimize the entire power system, rather than just battery consumption?
- Is it wasteful to use power assist in a high gear?
- Why should power levels be any different than matching gears to hill steepness?
- Should Pedal Assist Levels (PAL) correspond to each gear?
